Description
Technical field
The utility model relates to bicycle accessories technical field, particularly a kind of bicycle use back claw.
Background technology
The hook grippers of bicycle has the function of fixing trailing wheel, standard bicycle vehicle frame and related accessory are generally as aluminum alloy etc. is made by metal material, although the high but vehicle body weight of its rigid, do not meet road sport car or the requirement of mountain bike weight-saving, afterwards along with a kind of light weight, the appearance of the fiber reinforced composite material that intensity is high, bicycle manufacturer adopts fiber reinforced composite material to be processed to form vehicle frame, solve the problem that vehicle body is heavy, but its cost is high, in order to ensure that junction intensity needs to be provided with sleeve pipe at hook pawl and vehicle frame junction, its assembly precision to vehicle frame requires high, increase the weight of further to hook pawl weight.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bicycle use back claw.
The utility model solves the technical scheme that its technical matters adopts: a kind of bicycle use back claw, comprise hook corpus unguis, its obtuse angle end has a hook hole in order to pivot joint trailing wheel, described hook corpus unguis is by first connecting rod, form with the substrate of first connecting rod head one, described hook hole is arranged on described base plate bottom, reinforcing bar is connected with between described base plate bottom and described first connecting rod afterbody, described reinforcing bar and the back side, described substrate junction are provided with towards the lower breach hooking corpus unguis front, described reinforcing bar and the back side, described first connecting rod junction are provided with the upper breach of lateral opening towards oblique upper, described lower breach both sides angle is 120 °, described upper breach both sides angle is 120 °, the runners for fixing disc brake is provided with on rear side of described first connecting rod two ends, described runners end is provided with the screw for connecting disc brake, described substrate and described first connecting rod angle are 110 °.
On hook corpus unguis, arranging both sides angle in above-mentioned design is the upper breach of 120 ° and lower breach, and low to the accuracy requirement of vehicle frame during equipment, it can be suitable for variety classes vehicle frame; Described reinforcing bar and substrate and described first connecting rod angle are 110 ° and effectively strengthen hooking corpus unguis intensity.
As the further improvement of the design, described reinforcing bar is V-arrangement, and described reinforcing bar wedge angle is towards substrate and first connecting rod junction, and the turning of described reinforcing bar is 150 °.The turning of described reinforcing bar is 150 ° and contributes to improving further hooking corpus unguis intensity.
As the further improvement of the design, described lower breach and described upper indentations bottom are step-like, are convenient to vehicle frame and weld with hook corpus unguis, increase vehicle frame and the face of weld hooking corpus unguis.
As the further improvement of the design, described runners and first connecting rod junction bend towards connecting rod front, and described runners is connected section with first connecting rod be Z-shaped, prevent runners and disc brake from interfering, and are convenient to the brake disc installing different specification size.
The beneficial effects of the utility model are: it is the upper breach of 120 ° and lower breach that the utility model arranges both sides angle on hook corpus unguis, and low to the accuracy requirement of vehicle frame during equipment, it can be suitable for variety classes vehicle frame; Described reinforcing bar and substrate and described first connecting rod angle are 110 ° and effectively strengthen hooking corpus unguis intensity.
